What the model said

I'd recommend **#f5f5f5** — a light gray that's easy on the eyes, provides good contrast for text, and works well for most interfaces and documents.

If you want something warmer, try **#f8f9fa**. For a clean white, **#ffffff** works but can feel harsh; softer whites like **#fafbfc** are easier to read against for long periods.
